| hi! how is the proper use of vermiculite? is it ok to put more vermiculite on potting soil i just bought? |
| Vermiculite, and its substitute Perlite, are both naturally occuring minerals that are heat treated and expand to 20 times their original volume. They are both inert and help soil-less mixes retain water and aerate the mix. The only real difference is that vermiculite breaks down a little sooner than perlite. You can add vermiculite to your potting soil, but don't go overboard. Vermiculite will float to the surface if your potting soil mix is too light! |
